This is what I see in the Develop module after installing Lightroom 6. Lightroom 5 runs fine on the same Laptop. Is this a GPU issue? Configuration issue? End user issue? I'm running a Lenovo T430 with Windows 7 Enterprise 64BIT. I purchased and installed LR 6.0 22-April-15.
OK, solved my own problem. I went to Preferences... Performance and unchecked "Use Graphics Processor" option. Evidently my Lenovo T430 GPU is too old for Lightroom to use, even though it tried to use it.
I too have the same problem in lightroom CC as you ( after updating on 30/4/15 ) and have looked all over the internet. I had read something in the Adobe forum site suggesting a problem with the Graphics Processor, but it was not specific to our problem in lightroom. When I also checked photoshop ACR, it too showed the same as your screen shot. And all worked OK in lightroom 5 and photoshop 2014. It did not seem to make any sense at all ! I haven't unchecked " use Graphics Processor" option, but I will soon after I reply to you and had a rest after hours of trawling through internet sites looking for the answer. I use win 7 home premium desktop 64 bit on a 1 year old PC.
